Abstract
Abstract A method is provided for snagging a surgical suture wherein a device is introduced to the interior of the patient's body through a cylindrical cannula. The device includes a resilient loop which collapses as it passes through the cannula. The loop is crimped at its end whereby when a length of suture material is passed through the loop and the device is withdrawn from the patient through the cannula, the suture is snagged within the crimped portion so that it does not escape the loop.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
154 words
A method for snagging an end of a surgical suture located within a patient's body during arthroscopic surgery, comprising the steps of: deploying a distal end of a cylindrical cannula adjacent the end of said suture within said body; passing a resilient loop through the cannula from a proximal end thereof towards said distal end of said cannula into said body, said loop being secured to a distal end of an elongated rod and having a portion which is crimped at a location opposite to where the loop is secured to the rod; inserting the suture end through said loop as the loop extends beyond the distal end of the cannula within said body; and withdrawing the rod and the loop from the cannula whereby the end of the suture is snagged in the crimped portion of the loop and then is displaced so as to emerge from the proximal end of the cannula.
Claim 2
Independent Claim
154 words
A method for snagging an end of a surgical suture located within a patient's body during arthroscopic surgery, comprising the steps of: deploying a distal end of a cylindrical cannula adjacent the end of said suture within said body; passing a resilient loop through the cannula from a proximal end thereof towards said distal end of said cannula into said body, said loop being secured to a distal end of an elongated rod and having a portion which is crimped at a location opposite to where the loop is secured to the rod; inserting the suture end through said loop as the loop extends beyond the distal end of the cannula within said body; and withdrawing the rod and the loop from the cannula whereby the end of the suture is snagged in the crimped portion of the loop and then is displaced so as to emerge from the proximal end of the cannula.
Claim 3
Dependent Claim
41 words
A method as set forth in claim 1, wherein said loop is substantially elliptical in shape, the width of the loop being greater than the inner diameter of the cannula whereby the loop is compressed when it passes through the cannula.
